Well, the work on the spindles turned out pretty good and it might stay that way until I sort out an adjustable drag.
Yesterday, when removing the spindles, I noticed that the bushings are already at the end of their useful life, but I can't reproduce these because they are too thin and I ran out of raw material.
After all the adjustment, the left wheel continued to scrape the drag link a little less... and the right one started to touch, which did not happen before.
So I reversed the drags and... BINGO!!!
More and more I hate those who did maintenance before me...
